The 60–70 m³/h Oil‑Free Oxygen Booster Compressor is a specialised reciprocating piston unit designed to elevate low‑pressure oxygen (3–4 bar) from PSA generators, cylinders, or pipelines up to 150–200 bar for cylinder filling or direct use. Featuring a 100% oil‑free compression chamber with all‑stainless steel gas‑contact components, it guarantees zero hydrocarbon contamination and high purity. Operating at a low speed of 260–400 RPM with a 22 kW power range, this air‑cooled or water‑cooled booster ensures quiet, energy‑efficient, and long‑lasting continuous service.
Why choose 60~70 m³/h Oil‑Free Oxygen Booster?
1. High purity requirements – even trace oil vapour can ruin medical/food products and fail inspections. → 100% oil‑free compression with stainless steel wetted parts ensures ISO 8573‑1 Class 0 – zero hydrocarbon contamination.
2. Explosion risk with oxygen – oxygen reacts violently with hydrocarbon oils, making oil‑lubricated compressors unsafe. → Oil‑free design using self‑lubricating materials, plus built‑in over‑pressure and over‑temperature protection, delivers intrinsic safety.
3. High energy costs – compressing from atmosphere to 150 bar is very power‑intensive. → Boosts from 3–4 bar pre‑compressed oxygen, lowering the compression ratio; 22 kW power consumption saves significant electricity versus single‑stage units.
4. Frequent maintenance and downtime – oil systems require regular oil changes, filter swaps, and separator servicing. → No oil system; low speed (260–400 RPM) extends piston ring/valve life (up to 4,000 hours), reducing maintenance frequency and downtime.
5. Limited floor space and high noise – large, loud compressors are hard to install near workspaces. → Compact footprint (1950×1350×1400 mm) with forklift slots; noise <75 dB(A) – fits in workshops or stations without soundproof enclosures.
6. Inability to run 24/7 continuously – some units overheat or wear out under heavy continuous duty. → Designed for heavy‑duty continuous operation with air or water cooling, supporting 24/7 uninterrupted production.
7. Complexity of multiple small units – parallel boosters take up space and complicate controls. → Single integrated unit delivers 60–70 m³/h directly, simplifying piping, controls, and maintenance.
8. Unstable inlet pressure – upstream PSA output fluctuates, affecting booster performance. → Built‑in low‑inlet and high‑discharge pressure protection automatically monitors and shuts down to maintain stable output.

Application Industries
Steelmaking – Key for blast furnace and converter operations, supporting combustion and impurity removal; 60–70 m³/h suits medium‑sized mills.
Chemical production – Used for oxidation, cracking, and synthesis reactions (e.g., olefins, hydrogen peroxide, ethylene oxide), improving reaction rates and yields.
Glass manufacturing – Oxygen‑enriched combustion boosts efficiency, cuts fuel use and NOx emissions; also used for cutting and polishing.
Wastewater treatment – Supplies oxygen for microbial metabolism in activated sludge and biofilm processes, and for advanced oxidation in industrial effluents.
Aerospace – Provides breathing oxygen for pilots/passengers and pressurises liquid oxygen for rocket engines.
Energy – Applied in coal gasification, natural gas liquefaction, fuel cells, and oxy‑fuel combustion for CO₂ capture.
Food processing – Used in modified atmosphere packaging (MAP), fermentation, and food‑grade oxygen for preservation.
Papermaking – Supports pulp bleaching and oxygen demand from VSA oxygen generation.
Oil & petrochemicals – Used for oxidation reactions, pipeline testing, and gas injection/storage.
Pharmaceuticals – Provides high‑pressure pure oxygen for fermentation and drug synthesis.
Metalworking & cutting – Supplies high‑pressure assist gas for oxy‑fuel, laser, and plasma cutting, increasing temperature and cutting speed.
Air separation units – Compresses oxygen from fractionation columns for downstream processes.
Other applications – Mine breathing cylinder filling and high‑pressure pipeline/pressure vessel testing.
FAQS
FAQ 1: What makes this booster different from a standard compressor?
A: It takes already‑generated low‑pressure oxygen (3–4 bar) and boosts it to 150 bar for cylinder filling or industrial use. A standard air compressor cannot handle oxygen safely – it would create contamination and explosion risks.
FAQ 2: Why is oil‑free design so important for oxygen?
A: Oxygen reacts violently with oil – even tiny traces can cause explosions. Our oil‑free design uses self‑lubricating materials, so the output is 100% pure and safe for medical, food, and industrial applications.
FAQ 3: How much electricity does it consume?
A: Only 22 kW – significantly less than a single‑stage compressor that would need to compress from atmospheric pressure. Because it starts from 3–4 bar inlet, it saves you substantial energy costs over time.
FAQ 4: How often does it need maintenance?
A: Piston rings and guide rings last up to 4,000 hours; major overhaul is typically at 8,000–10,000 hours. No oil to change – just inspect wearing parts and replace as needed. Maintenance is simple and infrequent.
FAQ 5: Can this unit run 24/7 without stopping?
A: Yes – it's built for heavy‑duty continuous operation. With air or water cooling and robust construction, it runs stably 24 hours a day, 7 days a week, without interruption.
